Patent JP-H0240827-A (JP)
Title: Compact size electromagnetic relay
Inventor: KOBIYAMA HARUO
IPC: H01F7/14
Filed: 1988-07-29
Abstract: PURPOSE:To extend the span in which a movable spring is operate and to improve the performance by providing one side terminal to form a break and a make contact, and the movable spring to which an armature is installed integrally through an insulator. CONSTITUTION:When the enforcement of a coil is released, a movable spring 26 is moved upward by a break card 23c, and a break contact is closed. On the other hand, when the coil is enforced, the movable spring 26 is moved downward by make cards 23a and 23b, and a make contact is closed. In other words, the movable spring 26 is slided between the cards 23a and 23b and the card 23c by its flexibility. In this case, the movable spring 26 is not fixed other than a fixing surface 30, and furnishes a span from a fulcrum P on the fixing surface 30 to the other end Q, operating effectively. As a result, since the span of the movable spring 26 is made large enough, the stiffness is reduced, the load of the spring is decreased, and a high sensitivity can be acquired.

Title: Output circuit of a/d converter
Inventor: TAGUCHI MASAAKI
IPC: H03M1/12
Filed: 1985-08-30
Abstract: PURPOSE:To prevent the display of an inaccurate digital conversion signal by utilizing a busy signal and an over signal outputted from an A/D converter. CONSTITUTION:When integration is applied, a control circuit 23 of an A/D converter 2 generates a busy signal (F). When the level of an input signal is larger and the inverse integration is not finished within a prescribed time, an over signal (G) having a prescribed time width is generated. While the A/D converter 2 is operated normally, no output is given from an AND element 6, and when the input is excessive, the over signal is outputted, the output of the AND element 6 goes to '1' to invert the signal at the output (K) of a D-FF 8. As a result, a gate circuit 5 is controlled to prevent a digital conversion signal from being sent. A counter 9 is cleared normally and counts a signal every time the signal enters a chip enable terminal and its output clears the D-FF 8.

IPC: G11B20/18
Filed: 1987-07-30
Abstract: PURPOSE:To prevent the erroneous signal error detection due to an exclusive signal used for detecting the signal error by applying time division to a received data, storing the result in plural storage means and comparing all the data to detect the signal error. CONSTITUTION:An output data (a) of a high-order circuit is supplied to latch circuits 1-3, and a data output signal (b) is given to a latch selecting circuit 4. Time division data (d), (f), (h) being outputs of the latch circuits 1-3 are supplied to a comparator circuit 5, which compares the time division date (d), (f), (h) and brings a data error detection signal (j) to a level '1' when they are all coincident, and brings it to a level '0' when they are dissident. Thus, the signal error can be detected without using any exclusive signal, and the occurrence of erroneous signal error detection due to the unexpected erroneous change of the exclusive signal itself used for detecting the signal error is prevented.
